【摘要】 本文提出一种能用同一样品测定共振区和非共振区的微波张量磁化率和有效线宽的方法。在此方法中,将外加稳恒磁场旋转,与微波磁场形成一定的夹角,以调整被测样品对谐振腔的影响。同时将Patton采用的计算有效线宽的迭代法,推广用来计算微波张量磁化率各组元X~e,X_α~β和正。负圆偏振标量磁化率X~β等。本文还介绍了测量装置和测量结果。更多还原

【Abstract】 This paper suggests a method of measuring the microwave tensor susceptibility and the effective linewidth using the same sample in both the non-resonanee and re-sononce regions. In this method the applied steady magnetic field can be rotated to form a certain specified angle with the microwave magnetic field, so that the effect of the measured sample on the quality factor of the resonant cavity can be adjusted. The iterative method used by C. E. Patton in the calculation of effective linewidth is extended to the calculation of the components of microwave tensor susceptibility. A brief description of the experimental set and the results of the measurements are presented.更多还原
